Determination of mercury in marines sediment with cold vapor in atomic absorption spectrometry technique
Written by sctunisie no commentsCold vapor in atomic absorption spectrometry technic allows the determination of mercury at low levels. In sediments, mercury occurs generally in sulfur or in the organic forms, this latter is linked to the micro-organism activities. Thus an appropriate procedure for sample digestion is required. Among the nombrous method of digestion included in the literature we retain the acid mixture procedure [HNO3/HCl (3/1)]. After optimisation of the procedure of analysis, sediment samples collected from different ports in the Gulf of Tunis revealed that concentrations of mercury are in the range of 300-900 ng/g.
